Autoloader for Priv att variant

I have a priv that got into a boot cycle, so I decided to use an autoloader to wipe it and start fresh. However, the phone is unlocked and thus when I use the autoloader it states: "Loader is not valid for this device variant, the device variant detected is att. Please obtain a loader which supports the device variant above and try again." I did a little searching and it seemed like there wasn't a solution. Has there been any updates that I didn't notice? Is there an autoloader that I can get that will work?
